Filed: 1980-01-17
Abstract: PURPOSE: To raise the selectivity and yield of the desired substance, by using a specific metal oxide as a catalyst in preparing an isocyante by oxidizing an N- monosubstituted formamide with oxygen under heating.  
     CONSTITUTION: An N-monosubstituted formamide shwon by the formula I (n is 1W3; R is n functional organic residue) is oxidized in the presence of a catalyst comprising oxides of one or more metals selected from the group consisting of Ru, Rd, Pd, Ir, and Pt, to give an isocyanate shwon by the formula II. The reaction temperature is 200W600°C, preferably 250W500°C. The catalyst may be supported on a carrier, e.g., silicon carbide, etc. Especially a method wherein a raw material  in gas state together with oxygen is brought into contact with the catalytic layer continuously is preferable.

Title: Grating information removing device
Inventor: MOTOTANI KUNIHIKO
IPC: H04N7/18
Filed: 1983-01-11
Abstract: PURPOSE:To remove accurately grating information even if a body to be inspected shifts in installation position from a reference position and to attain miniaturization by providing a grating information measuring circuit, a grating signal generating circuit, a correlation measuring circuit, and a grating memory. CONSTITUTION:An image of the body 1 to be inspected is picked up by a TV camera 2 and coded into a binary signal by a binary coding circuit 3. The binary-coded signal is stored in a picture memory 8. A grating information measuring circuit 9 reads picture information out of the memory 8 to calculate the period, width, and initial phase of the grating information. The grating signal generating circuit 10 generates at least three difference kinds of grating signals (a)-(c) on the basis of the grating information obtained by the circuit 9. The correlative measuring circuit 11 calculates correlations with the signals (a)-(c) of the circuit 10 corresponding to rows or columns of the grating information from the memory 8 and stores a signal having close correlation in the grating memory 13. Thus, only the grating information on the body 1 to be inspected is stored in the memory 13. Therefore, when only the grating information on the body 1 is eliminated, the contents of the memory 13 are read out successively and the contents of the memory 8 corresponding to them are eliminated therefrom.

Abstract: PURPOSE: To measure easily in a shorter time and with less labor the length of an underground part of a pile driven into the ground, by applying oscillations to the pile in the direction of the length thereof, and measuring the resonance frequency.  
     CONSTITUTION: An oscillator 5 is started to actuate an oscillation application element 4. The frequency of the oscillator 5 increases with the lapse of time, and a pile 1 is oscillated in the lengthwise direction by the oscillation application element 4 at an oscillation frequency of the oscillator 5. The oscillations of the pile 1 is sensed by a detector 6 and converted to an electric signal, which is sent to an amplifier 7. An output from the amplifier 7 is recorded, as shown in a recorded curve 10, in a recorder member 9 of an X-Y recorder through a filter 8. The recorded curve 10 has peak values 11 0 , 11 1 ... at certain frequencies f 0 , f 1 .... Since the pile 1 has a sufficiently large length with respect to the diameter thereof, the length l of the pile is equal to a half of the wave-length of a minimal frequency f 0  at which a peak value 11 0  is recorded in the curve 10. Let C equal to the velocity of sound in the material constituting the pile 1. The length l of the pile can be calculated in accordance with a formula I, l=C/2f 0 . The length of the pile can thus be determined with ease.
